Description

It&rsquo;s interesting to hack one of your appliances or lighting projects into a whistle controlled intelligent one. The whistled allows you to do so by simply whistling two musical notes. To set it up, you just need to connect your 5.5/2.1mm DC connector on one end and your load on the other.
